rIVhe present invention relates to caps'for automobile radiators; andits robject is to provlde improved means for securing such caps to thenecks of the radiators ofauto-` mobiles.

This Vobject is attained by, andthe invention finds preferableembodiment in, the structure hereinafter particularly described in thebody of this specification and illustrated by the accompanyingdrawings,vin which e Figure 1 is a top plan view of a portion of a capfor an automobile radiator, shown partly in section taken on line 1-1 ofFigure 2; Y n

Figure 2 is a side view of the same applied to aradiator and shownpartly in section taken on line 2 2 of Figure 1;

Figure 3 is an axial sectional yview (enlarged) of a plug, taken on thesame plane;

Figure 4 is a cross sectional view of this plug and of a portion of t-hebody of the cap taken on line 4e4 of Figures 2 and 3; and

Figure 5 is an outer end View of the plug.

The radiator 1 of an automobile has an upwardly extending hollow neck 2through which water is supplied to ill'the radiator. This neck isthreaded at 3 (as .shown in Figure 2) and the hollow cylindrical body 4i of the cap surrounding this neck is threaded thereon and carries acover 5 for the radiator pivotally mounted at 6 on said body andcarrying means 7 for supporting a ther-k otally mounted at 10 on thebody 4 of the cap.

`In order to securely fasten the cap on the neck of the radiator andprevent its unauthorized removal therefrom, I provide a set screw 11threaded in the inner portion 12 ofan openingthroughv the side wall ofthe body 4, the inner end` of this screw, when screwed down, engagingand somewhat upsetting the threads of the neck 2 in the mounted positionof the capr on said neck; and in order to prevent tampering with andunscrewing this screw, I provide a plugl 13 which is inserted into theouter portion 14 of said opening and is held against removal therefromby a bolt 15 slidable in the transverse orifice 16 in the plug. The end17 of plug seen in Figure 2, is seated by its slid-A ing movement in asocket 18A in the body 4 portion of the opening. ToV insert the pluginto said opening it is turned half-way around from its position seen inFigures 2 and 3, whereupon the bolt slides to a position wherein it doesnot project from the orifice 16. When the plug is inserted into theopening it is turned half-way around, whereupon the bolt slides to theposition seen in Figures 2 and 3, so that its lower end 17 projectsbeyond the plug and is seated in the socket 18, thus preventing the plugfrom being withdrawn until all the parts are turned upside down,whereupon; the bolt slides so that its end 17 is withdrawn from thesocket. Stops 20, 21 are provided for holding the bolt in the orice 16of the plug in the bolts sliding movements, thus preventing the boltfrom becoming lost when the plug is not inserted into its operativeposition. The stop 20 is made by punching in a small portion of the plugso that the same projects into the orificeV 16, as shown in Figure 3.The plug is desirably provided at its outer end with a radiallyextending flange 22, to facilitate its ready handling, which flange hasa frangible portion 23 adjacent the body of the plug, such portion beingthus frangible in order that the flange will be broken ofi' if anattempt be madeto force the plug out of the opening and the bolt willVremain'unbroken and seated in the socket.

The invention being intended to be pointed out in the claims, is not tobe limited to or by details of construction of the particular-embodimentthereof illustrated by 'the drawings or hereinbefore shown or-described.

I claim: f

V 1. In a cap for automobile radiators: a hollow cylindrical bodysurrounding the neck of the radiator, carrying a cover therefor, andprovided with an opening through its sidewall having a lthreaded innerportion and an outer portion provided with a Vsocket in its side; a setscrew threaded in said inner portion and engaging said neck to lock thecapthereto; a plug slidably inserted into said outer portion and havinga extending-from the lower side Iof saidouter transversely extendingorice'; a bolt slidable in said oriice and into said socket, the

plug having stops to hold the bolt in said orifice in its slidingmovements.

2. In a cap for automobile radiators: a hollow cylindrical bodysurrounding the neck of the radiator, carrying a cover therefor, andprovided with an opening through its side wall having a threaded innerportion and an outer portion provided With a socket in its side; a setscrew threaded in said l0 inner portion and engaging said neck to lockthe cap thereto; aplug slidably inserted into said outer portion andhaving a. transversely extending orifice; a bolt slidable in saidorifice and into said Socket, the pluor having at its outer end aradially exten ing {lange with a frangible portion adjacent the body ofthe plug.

In testimony whereof I have hereunto set my hand at Grand Rapids,Michigan, this 5th day of September, 1923.

JOHN W. SEALOCK.
